Based on the long running manga of the same name by Sadao Shouji.

Kon Ichikawa's retelling of the classic true story of Samurai honor. When a young clan lord is forced to commit seppuku (ritual suicide), his loyal followers (now Ronin, masterless Samurai) dedicate their lives to avenging his death.

Set in an elementary school and centered on a boy named Takuya and a new transfer student named Saeko. Takuya's classmates think that Saeko has been possessed by Hanako, the ghost that lives in the bathroom. The rumor is especially encouraged by a girl who has a crush on Takuya and is jealous since Takuya likes Saeko.
